They've already demonstrated on-screen chemistry by kissing in public, and now two of the biggest movie stars in the world are taking their relationship one step further.

Meryl Streep and Sandra Bullock are attached to star in the next movie from Michael Patrick King, writer/director of the 'Sex and the City' films.

As if that's not enough star power, Oprah Winfrey also has a role in the (currently untitled) project.

The Universal Pictures comedy features characters at a home shopping network dealing with "marketing, marriages and the media," according to the studio.

With Oprah retiring her hugely popular syndicated TV show soon, will she be a draw for moviegoers?
